XL2543 – Analog-to-Digital Converter (ADC) – Xinluda
The Xinluda XL2543 is an 11-channel, 12-bit successive-approximation analog-to-digital converter (ADC) with a 3-wire serial interface, housed in a SOP-20 package. A TLC2543-compatible part available for RFQ at Pacific Component Xchange.
The XL2543 from Xinluda (XINLUDA) is a 12-bit, switched-capacitor, successive-approximation analog-to-digital converter (ADC) with an 11-channel input multiplexer and a simple 3-wire serial interface. Pin- and function-compatible with the industry-standard TLC2543, the XL2543 is a cost-effective drop-in option for multi-channel data acquisition, sensor monitoring, and embedded measurement designs. It is offered here as a Request-for-Quote (RFQ) item for engineers and buyers who need this hard-to-find converter outside the limited authorized-distribution channel.
Key Features
- 12-bit resolution, successive-approximation (SAR) architecture
- 11 analog input channels via an on-chip 14-channel multiplexer (11 inputs plus internal self-test voltages)
- Built-in sample-and-hold function
- 3-wire serial control interface: chip select (CS), I/O clock, and serial data input/output with 3-state output
- 10 us conversion time over the operating temperature range
- Linearity error of 1 LSB maximum
- On-chip system clock (4.1 MHz)
- Single-supply operation from 4.5 V to 5.5 V
- Programmable MSB/LSB-first output, data length, and power-down modes
- Operating temperature range of -40 C to +85 C (industrial)
- SOP-20 package; SSOP-20 variant available as XL2543-SS
Applications
- Multi-channel data acquisition systems
- Industrial process monitoring and instrumentation
- Sensor signal digitization (temperature, pressure, position)
- Battery and power-rail monitoring
- Embedded and microcontroller-based measurement boards
- TLC2543 replacement / second-source designs
Why Source XL2543 from Pacific Component Xchange
The XL2543 has little to no authorized-distributor availability, making it a challenging part to procure through conventional channels. Pacific Component Xchange specializes in sourcing hard-to-find, allocated, and obsolete components for engineers and procurement teams worldwide. We support legacy and second-source ADCs like the XL2543 with authenticity verification, global shipping, and responsive quoting. Submit an RFQ for the XL2543 today and our sourcing specialists will confirm current availability, lead time, and pricing for your required quantity.
